When you think 256GB may not be quite enough, this is a good option. It's fast too! Installed a fresh copy of Windows10 of my wife's laptop, which had 256GB used of her 500GB HDD (but that did include the extra partitions the OEM always installs) After moving her data files over, she ended up with about 70GB free.

ConsCanada Post was slower than normal. They had it one day more than normal, which made it show up after the weekend I needed it. Had to buy another SSD at a local store.

SummaryWhen you think 256GB may not be quite enough, this is a good option. It's fast too! Installed a fresh copy of Windows10 of my wife's laptop, which had 256GB used of her 500GB HDD (but that did include the extra partitions the OEM always installs) After moving her data files over, she ended up with about 70GB free.

SummaryThe is featherlight and easy to install, either in a top or bottom drive bay. The retail package includes a 9.5mm adapter if needed, and it formatted then installed my OS lightning fast. Highly recommended for a mid-sized SSD, but would obviously recommended an HDD storage in addition.

SummaryThanks to the extra 35 - 19 gigs compared to similar drives it has about 230 gigs free after having Windows 10 installed on it. Performance is no slouch and free Acronis make this a hard ssd to beat for the money

ProsGreat price.Good size for most laptops.INCLUDES a license key for software to migrate from a HD to the SSD!!! Most SSD purchases don't include this software and then you have to buy it!

Cons

SummaryExcellent product for a great price. I highly recommend buying this brand of SSD over the other brands because it includes the migration software for FREE to move your OS from your hard drive to the SSD. I've bought many SSDs and this is the first one that included this software!

ProsRuns smoothly for me. Includes Acronis if you need to re-image from a previous drive.

ConsAdapter trays not included.

SummaryFortunately I've built a small collection of adapter trays so 2.5" drives can be installed into my tower, but aside from that this is the third or fourth Crucuial drive I've bought, and I've had no negative experiences using any of them, other than actually starting to run out of space quicker than I anticipate (I stick with the lower sizes for maximum affordability).

SummaryA total plug and play experience. Performance is essentially identical to the original drive. I've kept the original drive with Windows 10 in case it is ever needed. Only two ways to make it better: lower the price or increase the size.

ProsGood performance, good pricing (275GB for the price of 240GB), excellent feature set (partial power-loss protection), superb power drain (or lack thereof)... all the same things you could say of the Crucial's previous BX100.

ConsDoesn't solve world hunger?

SummaryI LOVED the BX100, and was sad to see it discontinued. The replacement BX200 is still one of the worse performing SSDs on the market. The MX300 doesn't dethrone the Samsung 850Evo as the fastest 3D TLC SATA SSD, but overall, regains the title of best overall SSD value.

Crucial SSDs, from the M500 onward, have all contained partial power-loss protection. You won't have to worry about the SSD being bricked or the PC rendered unbootable with an unexpected power loss. It's not as robust as Intel's full power loss protection (only available in their higher end SSDs) that also covers in-flight data, but considering Crucial doesn't charge a premium for this feature, they've at an obvious advantage when the rest of the stats are competitive... and with the MX300, that is the case.

Most TLC SSDs write speeds crash pretty hard when you are initially copying over large amounts of data to them as you run out of the SLC cache. It's especially bad for the smaller 120GB/240GB class of drives, with the smaller BX200 dropping below 50MB/s! With the MX300 and its 3D TLC, even the smallest 275GB drive stays over 120MB/s at its worst... enough to keep up with most HDDs during the odd huge transfers.

Consnothing comes to mind. I saw reviews saying this drive has subpar random access. I haven't noticed it myself.

SummaryI bought this drive to revive an old laptop.

This is something like my 6th SSD so I'm not going to comment on how much faster it is than a normal hard drive. I will compare it to my older Intel 180 GB SSD installed on exactly the same lapotop to say that it is noticeably faster.

I installed from scratch and have had zero problems from installation to now a month later.

I own other SSDs that are supposed to be faster, but it's not really noticeable on day to day usage.
